Dear Marcello Pagano,

Hello. This is sunyoung jun, a second year graduate student in economics
at UCI. I'm running the nested logit model for the project. When I did 
it using the STATA, I received "unbalanced data" message. I tried to 
find some reference to overcome this problem, but I couldn't. Would you 
let me know if you have good references for this problem.

I'll really appreciate your help in advance.

Thanks a lot!


Sincerely,
